He may look like a panther, but he’s all jaguar. A rare black jaguar cub was born a couple of months ago at the Huachipa zoo in Lima. The unnamed youngster is the third of this endangered species to be born in capitivity in Peru. You can see his faint jaguar markings in another picture at Green Expander. Link -via Fark

Correction: Jess left a comment and told me something I did not know:

Black jaguars are panthers. Any jaguar, leopard, or cougar who is born black can be called a black panther.

I had always thought a panther was a black leopard only, but Wikipedia says Jess is right!
